Ezekiel 38:21-22

21I will call for a sword against Gog throughout all My mountains,” says the Lord God. “Every man’s (invading soldier’s) sword will be against his brother (ally) [in panic and confusion].

22With pestilence and with bloodshed I will enter into judgment with Gog; and I will rain on him torrents of rain with [great] hailstones, fire and brimstone on his hordes and on the many nations that are with him.
